5.4 (E) Environment setting parameters
5.4.1 Real time clock function
The time can be set. The time can only be updated while the inverter power is ON.
The real time clock function is enabled using an optional LCD operation panel (FR-LU08).
Simple clock function
• When the year, month, day, time and minute are set in the parameters, the inverter counts the date and time. The date
and time can be checked by reading the parameters.
• The clock's count-up data is saved in the inverter's EEPROM every 10 minutes.
• Because the date and time are cleared after turning OFF the control circuit power supply, the clock function must be reset
after turning ON the power supply. Use a separate power supply, such as an external 24 V power supply, for the control
circuit of the simple clock function, and supply power continuously to this control circuit.
• In the initial setting, inverter reset is performed if supplying power to the main circuit is started when power is supplied only
to the control circuit. Then, the clock information stored in EEPROM is restored. Reset at the start of supplying power to
the main circuit can be disabled by setting Pr.30 Regenerative function selection. (Refer to page 553)
• The set clock is also used for functions such as fault history.
